To measuring the soil removal performance of oven cleaning products used in the home.
The test was performed on artificially applied soils on porcelain substrates. The experiment was based on the guidance from CSPA DCC-12 Screening the Efficacy of Oven Cleaners. Soil B from the standard was made using 85.4 wt.% butter, 6.5 wt.% sugar, 4.3 wt.% deionized water and 3.4 wt.% flour. The sugar was dissolved in water between 75 and 95 F. Then at room temperature or above, the softened butter was added to the solution and mixed thoroughly. Flour was added to the mixture and stirred until a uniform mixture was obtained. A uniform weight was applied to each of the twelve preweighed porcelain coupons. The coupons were then covered with aluminum foil to prevent air currents from disturbing the soil film during baking. The soil was aged in a preheated 475 F for 120 minutes. Once coupons were cooled to room temperature, dirty weights were recorded.
Cleaning was performed following the instructions on the supplied commercially available product. Product was sprayed onto the surface and allowed to soak for two hours and then wiped clean with a cloth. Final weights were recorded and effectiveness was calculated.

Success Rating:Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
The PLZ Fresh & Clean Heavy Duty Oven Cleaner performed on the same level as the commercially available EasyOff Fume Free oven cleaner. The Easy-Off Heavy Duty Oven Cleaner was the least effective and second least consistent product evaluated after PLZ Oven Fume-Free. It was especially lacking when compared to its PLZ counterpart, PLZ Fresh & Clean Heavy Duty Oven Cleaner, which performed nearly 30% more efficiently.
